Participatory ergonomics in a red meat packing plant. Part II: Case studies.

Three ergonomics-related case studies are presented to demonstrate the problem-solving method used by two participatory ergonomics teams. The problem-solving method was adapted from principles related to quality management (e.g., participation, structure, a scientific approach, and decision by consensus). The first two steps of the problem-solving method were related to identification and evaluation of the problem; the latter three steps were related to solution development, implementation, and evaluation. The problem evaluation process included the collection of background, exposure, and effects data. Solution development following evaluation of the problem started with a brainstorming session, then discussion to select interventions by consensus. The format for presenting the case studies was intended to be concise and visual with the intent of effectively documenting the teams' problem-solving processes.
